1997 Class C Winnebago, 47,000 miles too old to buy?

Bummer, not getting a good feeling about the “history” is the first reason to be skeptical of an old vehicle.
There’s plenty of them out there though.
Consider deals like the above a good opportunity for a low ball offer though.
Generally the bad problems don’t result in a check engine light though, but it’s a good excuse for a low offer if the owner can’t or won’t keep up with servicing and repairing the vehicle.
